CHANGELOG
Version 2.1, released 01-Jul-2007
Fixed blocking of insert / delete / apply operations when open in read_only mode
Imported setup_combo() from Gtk2::Ex::DBI - setup & requery a combo
Added on_row_select key to run external code when a row is selected
Fixed text of error message when closing a windows that had an 'un-applied' datasheet
Don't include identity columns in insert / update SQL ( fixes SQL Server updates )
Added support for setting individual fields read_only
Renamed column_value() to get_column_value() and added alias
Added set_column_value()
Renamed column_from_name() to column_from_sql_name ( and add legacy support )
Don't append a primary key column if one is already defined
Fixed warnings when hiding the status column ( don't set width to 0 )
Fixed warnings when searching for a primary key ( uninitialised value )
Renamed packages for custom cell renderers from MOFO:: to Gtk2::Ex::Datasheet::DBI::
- even though the MOFOs still don't work :)
Queue iter deletion until the end of the apply() method ( otherwise can't move to next )
Added before_apply key to object constructor, to run external function before applying
- return 1 to allow update, return 0 to abort update ( and continue with next record )
Added 'no warnings' directive and commented out 'use warnings'. Switch around if you want warnings
Added 'align' key to field hash - use either a string or a decimal from 0 to 1
Default to right alignment for number fields
Added DOUBLE to the list of numeric fields
Added 'access_time' renderer to deal with weird MS Access formatted time values
( 1899-12-30 hh:mm:ss ) format - ie ALL times have 1899-12-30 prepended to them
Allow setup_treeview() to continue without a primary key, but force to READ-ONLY
More verbose and prettier warnings
Added missing documentation for foreground_colour key in fields hash
Fixed warnings when rendering a date cell with a NULL date
Added support for pass_through queries that return a recordset ( including stored procedures ) - read_only
Better detection of DATE column types from column_info ( use regex instead of exact match )
Optimisation: Use stock gtk2 text renderers where possible ( ie when read-only )
Added support for hard-coding a cell's background colour ( ie a field's background_colour key )
Added sum_column() function, which returns the total off all values in the given column
Added support for custom_cell_data_func - a user-defined function for formatting cell data
Added 'quiet' flag to supress non-fatal warnings
Added parser for SQL Server default definitions
Allow 'faked' column_info hash to be passed into constructor
Exclude the primary key column in updates for ALL databases
( also just use our $self->{primary_key} field to detect the primary key column )
Fixed failure in setup_treeview() when column_info() fails
Don't worry about detecting more than 1 primary key from column_info()
- it doesn't work on multi-table queries anyway
Added friendly_table_name key to constructor for use in dialogs ( imported from Gtk2::Ex::DBI )
Added support for setting up chains of functions to be attached to a cell's custom_cell_data_func
Added dd-mm-yyyy support to CellRendererDate
Fixed incompatibility between us, CellRendererDate and gtk+-2.8.18+
Re-implemented date_only renderer with a builtin_render_function
- this is to deal with SQL Server's combination datetime fields when we only want a date
Mark columns with a currency builtin render function
Strip out dollar signs and commas from currency columns when applying, in get_column_value, and in sum_column
Attached $self->{columns} ( Gtk2::TreeViewColumns ) to $self->{fields} ( and removed $self->{columns} )
Store width of each column whatever in 'current_width' ( ie $self->{fields}[_field_no_]->{current_width} )
Rename size_allocate() to on_size_allocate()
Added support for using pango markup in the column heading, via a field's header_markup key
Store column name in the treeview_column hash so we can easily figure what what column someone's clicked in
Major reorganisation of $self->{fieldlist}, $self->{fields} and column handling to avoid off-by-one BS with status column
Work-around for http://bugzilla.gnome.org/show_bug.cgi?id=317387! Woot!
Removed Number::Format dependancy - doesn't install well under Windows
Added count() function, with optional conditions ( similar to sum_column() )
Optimised column_from_column_name and setup_treeview
Fixed focus-out-event in custem CellRendererText not triggering the 'edited' signal. Finally. Thanks Muppet :)
Fixed cell editable height problem in gtk-2.10.x. Thanks Torsten :)
Fixed setting up primary_key_column and primary key in field list if a primary key is passed ( ie if column_info fails - very rare )
Ported data lock functionality from Gtk2::Ex::DBI, adding functions:
lock()
unlock()
Automatically scroll the treeview as the cursor changes
Copy a cell's font size to the editable when editing ( currently fixed at Arial though )
Update CellRendererDate to accept font sizes

Added GST removal and rounding to calculator
Added on_changed functionality ( gets passed { treepath => $treepath, iter => $iter } )
Pass model and iter to before_apply() and on_apply() functions
Added DBD::SQLite support
Added ( slightly buggy for some data, but hey ... ) initial column sorting support. Double-click in column headers to sort

Fixed header alignment for datasheets that aren't visible when being constructed
Added support for custom dialogs when datasheets need applying
Added icons to all dialogs

Better currency formatting
Added max_column() function

Added detection of primary key columns
Other patches and suggestions merged
Simplified primary key detection
Allow 'faked' column_info hash to be passed into constructor

Added detection of primary key from column_info() ( MySQL & SQL Server only at present )
Added destroy method, which destroys all signal handlers we've created, then destroys itself
( not working yet )
Renamed $model_setup->{table} to $model_setup->{from} in dynamic models
Added legacy mode to support 1.x requests
Process dynamic models out of order when querying - no need to queue them for later
Added method revert(), which is a synonym of undo()
Added graceful handling of failure of $dbh->column_info ( warn to console what's happened )
Warn to console if $dbh->column_info fails AND we don't have a primary_key definition
Only ask to apply changes if not read_only
Addded missing schema request to self
- harmless anyway because we only support automatic renderer selection for MySQL currently
Updated documentation & cleaned up POD somewhat

Added dump_on_error flag to dump SQL on a DBI error
Converted more 0s to FALSEs
Version 0.9, released 16-Sep-2005

Removed more Perl warnings re: uninitialised use of ...
Choose string / numeric comparison based on database field type for combo renderers
Rename 'none' renderer to 'hidden' ( and still support old 'none' renderers )
Use text renderer for hidden columns ... so we can point dynamic combos at them and catch changes
Version 0.7, released 02-Aug-2005
Added support for dynamic combos - ie combos whose options depend on the current row
Disabled MOFO::CellRendererSpinButton ... not exactly working properly yet
Add support for CellRendererCombos with a string ID ( previously only supported int IDs )

Added column_value to look up a value in the selected row

Added support for CellRendererCombo - thanks muppet :)

Ported to Gtk2::ListStore / Gtk2::TreeView
( only supports text cell renderers currently )
Renamed sql_fields to sql_select and changes requirement back to and SQL select statement
